Seachem Reef Iron

Seachem Reef Iron is an iron supplement for reef aquariums that supports the growth and coloration of corals and macroalgae by enhancing iron levels, which assists in nitrogen uptake.

  • Iron Supplement for the Reef Aquarium
  • Concentrated 5,000 mg/L Iron
  • Supports Growth and Coloration
  • Assists in Nitrogen Uptake

Iron is an essential element required in metabolic processes, protein synthesis, and growth of corals and macroalgae. Iron supplementation can enhance coral and macroalgae growth and color – particularly yellow and green colors in corals. In systems supported with nitrogen and phosphorous supplementation, iron utilization rates may be increased as iron assists in assimilation of nitrogen.  

Iron supplementation can enhance coral and macroalgae growth and color – particularly yellow and green colors in corals.

Supplementing with Reef Iron™ provides a safe means of increasing iron concentrations. Reef Iron™ is ideally suited for use with an aquavitro® sentia™ dose doser to maintain iron at a consistent concentration based on your aquarium's unique demand but is easily dosed manually as well. Ideal iron levels will vary but natural seawater generally ranges from 0.003–0.01 mg/L iron. Reef aquariums are often kept at higher levels for optimal coloration and growth. For optimal macro algae growth, many find 0.05–0.1 mg/L to be beneficial. Use Reef Nitrogen™, Reef Phosphorus™ and Reef Potassium™ to maintain optimal nitrogen, phosphorus and potassium levels.

Directions:

Beginner
Use ½ cap (2.5 ml) per 160 liters (40 US gallons) twice a week or as needed to maintain desired iron levels.

Advanced
The beginner dose raises iron by 0.08 mg/L. To target a specific iron level, increase dose according to the following formula: 0.195vn=m where v= volume of tank in liters, n=desired iron increase, and m= volume of product to use in ml. For example, to raise 160 liters by 0.08 mg/L iron you would use 0.195*160*0.08 resulting in 2.5 ml to dose. For reference: 1 US gallon=3.8 L.

The pants are of excellent quality
Size: XX-Large, Color: Mauve/Apples
The pants are of excellent quality, made from thick material that feels very warm. By comparison, the long-sleeve T-shirt is thinner and not as warm as the pants.
